I'm trying to generate an arithmetic and geometric series/sequence with JavaScript.

I try to generate an average arithmetic and geometric
series/sequence with JavaScript. The thing that makes this challenge is that
I use user input to determine the parts of the formula that I use for
generate each sequence. I tried running the formulas, but I learned that I was
channels running through them and not numbers. How to generate my
sequences/series and always use user input? PS, here's my formulas: (a1-East
first term, d and r are difference/ratio, and n is the n-th term)

1.) a1 + d * n  

2.)a1 * r^n

Entry user of a form is always a string. There are several ways to convert a string to a number in JavaScript:

  • Pass it as an argument to Number()
  • Pass it as an argument to parseInt() (for an integer)
  • Pass it as an argument to parseFloat() (for a floating-point number)

  • X 220 and Mini Series 3 with USB 3.0

    Hello

    I am recently received a Mini Series 3 with USB 3.0 for my laptop company ThinkPad X 220 Windows 7 64 bit.

    However, after installation of the USB 3.0 driver downloaded from the Lenovo Web site, I still do not see USB 3.0 in my Device Manager device.

    I have also some test using an USB3.0 external HDD but the USB 3.0 port seems to have exactly the same speed as all the other ports.

    How can I activate USB3.0 on this Docking Station?

    Thank you

    Jeremy

    ThinkPad X 220 with i7 (i3 and i5 has usb 2.0 ports only) has a single USB 3.0 port, but the way it is connected through the motherboard, it is unable to support port additional usb 3.0 from the dock.

  • Open and close the Popup with Javascript

    Using Apex 3.2

    I probably have done this lots of times in my old job, but do not have access to the code and now I can't work properly.

    I opened a window pop up with javascript
    Now, I need to close and refresh the calling page, but only if it ratifies the validation on the popup.
    I have an item hidden on my pop up called P7_FLAG.
    I have a process page after validation that affects P7_FLAG (only the value 1, if passes validation).
    I also have a "SUBMIT" button.

    So once I click my button "SUBMIT" page should look at validations, so ok, P7_FLAG the value 1, then close the popup and refresh the calling page.

    My current look of javascript like this
    <script type="text/javascript">
    function saveChanges(){
    doSubmit('SUBMIT');
    var test = $x('P7_FLAG').value;
    if(test == '1')
    {
    window.close();
    window.opener.doSubmit('REFRESH');
    }
    }
    </script>
    My button
    javascript:saveChanges();
    The problem is that I need to click twice on the button SUBMIT.
    First, it sets P7_FLAG
    Second time, it closes page and refreshes.

    I probably made a fundamental mistake, but today I can't.

    See you soon

  • I'm trying to generate a chm on the net and I get a compilation error message

    Hi all

    I am trying to generate chm over the net, and the project even when I'm generating the same chm locally works fine, but when I try to generate the same chm on a network location, it gives me a compilation error and give up the generation. It is also to keep the chm open subsequently file, so I have to reboot the machine.

    It is not a question of project. RoboHelp is simply not designed to work this way, but like many things, some people can use them out of what they were designed for. However, just because some people can work this way, it follows not everyone can.

    I've seen people with projects on a network, and they say they have been doing it for years, it must be OK. A while later, they come back and say that the problem is solved since arriving it locally.

    Sorry, but it seems that you're stuck with working like you do or get your colleague to do so. It could be as simple as it is a bit different from your network.

  • The use of generate for demodulation and modulation PSK sync settings

    Hi I'm trying to generate Parameters.vi of sync allows you to synchronize the flows recovered after demodulation and my input to the block of modualtion streams but I do not know how to work with this block to synchronize the input with the output stream stream. Also would you please let me know what are the modes of synchronization of the input bits and demodulation bit stream. I really appreciate your help

    Thank you

    Hi en99,

    To use 'Synchronization generate MT Parameters.vi' you must wire in what follows on your block diagram:

    • The parameters of the system created in 'System generate MT Parameters.vi' needs must be connected directly to the vi synchronization.

    • Sync settings must be wired directly to 'MT Demodulate.vi'

    • The bits of synchronization can be connected to synchronization vi directly at "MT generate Bits.vi.

    What I did is took your 11. VI you downloaded in your post previous and amended to contain synchronization vi. I recorded as a 2010 version.

    I hope this information helps!

    Kind regards

  • Generate a report and save it as a PDF

    Hi all

    Attachment VI I work on.,.

    Here I am trying to generate a report by adding the chart picture in it and save the report in pdf format.

    But I coudnt able to save it as a pdf.

    In the path dialog box, even if I give the file name as. PDF, still i coundt able to print pdf and when I tried to open it became corrupt.

    Please help out of this

    I started on the path of 'save as PDF from the word' awhile, but I never got to complete the VI.  I think that you need to do is to use the "word get ActiveX References.VI" and document. SaveAs2 method (call the node).  You must connect an integer '17' to the variant "file format" entry.

  • FPGA to generate the counter and pulse train

    Hello

    I have some experience with Quartus, but new on the FPGA OR.

    I have a PCI-7811R. I'm trying to use it to illuminate sequentially 144 LEDs repeatedly. The duration of each pulse is 480us.

    Basically, I need to generate a pulse and generator of a counter to record the number of pulses and, according to this number, select which light is lit.

    I designed a pulse generator train based on an example of using FPGAS and added a counter in it. You can see in the attached vi.

    My question is,

    When I put the I/O node inside loops call single cycle, it can generate the correct pulse.  However, when I tried to use the local variable to transfer data from the SCTL and then plug it on another node of I/O, I can't detect the pulse signal when I measured this I/O.

    Is there something wrong with my code when I try to transfer the data of the SCTL? Can I also use local variable to transfer the value of counter, because I will need it in the next part.

    Thank you!

    If you are referring to the wired local variable to DIO2 in your attached VI, the problem is very simple: it is outside a loop, then it executes only once.  Put this local variable and the node of IO in a loop and I think you'll get something close to the impulse you expect (although if it is not in a loop of single cycle you will have exactly the same calendar).

  • Error while trying to generate the Proxy Services on OSB

    Hello

    I am developing some services on OSB, every service call stored procedures using a database of JCA adapter.

    I followed this tutorial:

    https://guidoschmutz.WordPress.com/2010/08/08/Oracle-service-bus-11g-and-DB-adapter-a-different-more-integrated-approach/

    Business service are ok, they work fine, I tested it directly from OSB.

    Problems when trying to generate the proxy service.

    The General configuration of the proxy after set the source of the wsdl and when I specify jca file proxy service, an error message returned:

    "Unable to update JCA transport invalid JCA proxy service. Transport exception occurred with the following message:
    Invalid JCA file for JCA proxy service. If you are creating a Proxy from a Business Service, please select a different transport type (for example, http). If not, JCA file must contain JCA activation spec properties."

    And here's my content created by JDeveloper jca file:


    < name of the adapter-config = "getApprover" = 'Database adapter' adapter wsdlLocation = "getApprover.wsdl" xmlns =" " http://platform.integration.Oracle/blocks/adapter/FW/metadata ">

    Is there someone who had attempted to use the JCA transport with database adapter already? Please give me a suggestion.
